Many animals undergo molting as a means of shedding their outer layer—feathers, hair, skin, or exoskeleton—so they can grow bigger or prepare for their next life stage. “It's a critical event in the life cycle of an organism,” says Donald Mykles, a biologist at Colorado State University.

Why do animals shed their outer skeletons?
Insects, spiders and shellfish are some of the invertebrates that have exoskeletons. The exoskeleton provides them with strength and support, as well as protecting the organs inside their bodies. To grow, animals with exoskeletons need to shed their old skeleton and grow a new one.
How animal shed their skeleton?
Molting is the process that occurs when animals shed their old skins or body coverings. Once they discard their old body covering, a fresh, new skin is revealed. This process is also known as shedding, but most biologists call the process ecdysis.
Why is molting of the exoskeleton necessary?
Moulting is necessary as the arthropod exoskeleton is inflexible and so, to grow larger, arthropods must moult. ... The new exoskeleton is soft and the arthropod can't move because its musculature is attached to this exoskeleton. Once the new exoskeleton has dried and hardened the animal can move again.
Why is molting necessary to some animals?
In arthropods, such as insects, arachnids and crustaceans, moulting is the shedding of the exoskeleton (which is often called its shell), typically to let the organism grow.
Do exoskeletons break?
Digestion of chitin
The exoskeleton of insects is composed of hard chitin, which is a polymer of acetylglucosamine and quite resistant to many chemicals. ... This is the most important enzyme as it breaks open the exoskeleton and hydrolyzes it firstly into chitobiose and chitotriose (Skoczylas 1978).
Where do snakes go when they shed their skin?
As soon as it is complete, the old skin peels away, leaving behind a snake-shaped shell along with any parasites that may have been attached. To leave their old skin behind, snakes may go for a swim to allow water to loosen the old skin even further.
Does molting hurt?
Avoid Stress & Handling
As humans we want to hug away the hurt, but not only is handling during molting stressful, it is also painful. The new feather shafts (pin feathers) are very sensitive and can be painful when touched. If the pin feathers are damaged, they can bleed profusely.
Which animal no longer lives on earth?
One the most amazing and giant animals to go extinct is the Woolly Mammoth. They survived through ice age, but were unable to survive the greed of humans. They are considered to be the ancestors of the modern day elephants.
Do Spiders shed their skin like snakes?
The key is molting. Like reptiles, amphibians and arthropods — from cicadas to crabs — spiders periodically "shed their skin" at key points in their life cycle.
Why does molting occur?
The molting process is triggered by hormones released when an insect's growth reaches the physical limits of its exoskeleton. Each molt represents the end of one growth stage (instar) and the beginning of another (Figure 1).
What animals shed their fur?
Animals who molt include reptiles, amphibians, anthropods, birds, and even a few arachnids, such as tarantulas.
Do humans molt?
But humans do molt. We shed hairs and skin cells. ... "Molting" means the periodic shedding of feathers, hairs, horns, nails, shells, and skins - any outer layer. Molt is from the Latin mutare meaning "to change".
Do Cockroaches moult?
Cockroaches moult several times throughout their lifetime, but unlike reptiles which shed a layer of skin, cockroaches moult out of their own skeleton. ... A cockroach has to moult as its hard outer covering, known as the exoskeleton, doesn't grow meaning it has to periodically develop a new covering underneath the old.
Do crabs eat their molt?
Crabs that are molting are not concerned with food and digestion. ... Once they complete shedding, they eat their exoskeleton and, because all nutrients from the exoskeleton are absorbed, the a crab eating its exoskeleton does not produce the amount of feces that an un-molting crab produces.
Do snakes molt?
A regularly recurrent event during the activity period of all snakes is the shedding, or molting, of the skin. ... At this point, the snake's eyes become a milky blue, an indication of a physiological loosening of the skin that forms the eye cap.
